San Bernardino County animal shelters are teaming up this weekend in Yucaipa to help homeless animals find homes at the second annual Homeward Bound Mega Pet Adoption Event.

From 10 a.m. to 4 p.m. Saturday and Sunday, hundreds of animals will be up for adoption from two dozen animal adoption agencies at Yucaipa Regional Park.

The participating agencies include San Bernardino County Animal Care and Control, Yucaipa Placement Society and the Redlands Animal Shelter, which participated in the effort last year and found homes for nine of the 14 dogs it brought.

“It was well set up and” the community response was good, said Redlands Police Officer Bill Miller, the city’s animal control supervisor.

This year the Redlands shelter is upping its goal by bringing along 20 dogs and 10 cats in need of homes.

“All mixed breeds,” Miller said. “A variety pack.”

In addition to adoptions, the event will double as a kick-off for the county Animal Care and Control Division’s participation in the ASPCA 2013 Rachel Ray $100,000 Challenge that began on June 1.

The county animal shelter, which is in Devore, is one of 50 in the United States competing for the grand prize. The event asks those participating to find homes or return lost pets to families. The shelter with the highest amount will win the cash prize.

“The (event) assists in meeting the health and social service needs of the county’s population and supports the Countywide Vision Statement where all sectors work collaboratively to reach shared goals,” said Brian Cronin, chief of county Animal Care and Control, in a news release. “By building new and expanding partnerships among public agencies, businesses and non-profit and faith-based organizations.”

Low-cost vaccinations and microchipping are also event highlights and will be available from 10 a.m. to 2 p.m. both days, thanks to the San Bernardino Valley Humane Society.

“Having your family pet vaccinated is so important and this is the perfect opportunity to not only take advantage of low-cost pricing, but to enjoy the event with your family at the same time,” said Jill Henderson, development and community outreach coordinator for the organization.

Parking will be available at the Jerry Lewis Soccer Complex, 34232 Oak Glen Road,
